Low complexity, high order multiple input, multiple output (MIMO) operations are described in which a user equipment (UE), configured with at least one normal performance receiver chain and at least one low-performance, low-complexity diversity receiver chain, signals a capabilities indicator identifying existence of the low-performance diversity receivers. Using the UEs capabilities, a serving base station may schedule uplink and downlink transmissions for the UE to reduce uplink-downlink collisions below a minimum threshold number. The serving base station may also take UE transmit power into consideration for signaling power control or modulation and coding schemes in order to minimize potential interference cause by UE transmissions. For channel state feedback, the UE may provide different channel feedback for uplink-downlink collision subframes and non-collision subframes.
